Aww this really touched me, and brought a tear to my eye,
I am too a mum of 2 I have never left my children but I feel your heart ache.
You was not well then, and all what matters now is that your there for them,
Children can have issues despite how there brought up.
Keep being the great mum that you are, you can't change the past but you can change the future.
Your kids will understand when they are older or have children of there own.
Big hugs too
